Silencing of circ0093740 inhibited the proliferation and migration ability of the Wilms’ tumor cells, and this mechanism is mediated by the sponging of miR-136/145 operated by circ0093740 that leads to the upregulation of DNA (cytosine-5-)-methyltransferase 3 alpha (DNMT3A), transcript variant 3. The gene discussed is DNMT3A; the disease is Wilms tumor.
